Siemens 42GF35AF 120V Contactor

Product Description

The SIEMENS 42GF35AF is a 120-volt contactor designed to switch and control electrical loads in HVAC, industrial, and commercial power-distribution applications. Contactors like this one serve as the primary switching device between a control circuit and a higher-current load circuit, energizing compressors, motors, and other heavy loads on command from a low-voltage or line-voltage control signal. Licensed electricians and HVAC technicians install this type of contactor as part of motor starters, air-conditioning systems, and general-purpose load-switching panels. Its 120-volt coil rating makes it compatible with standard line-voltage control circuits common in commercial and light-industrial installations.

This contactor is suited for residential and commercial HVAC equipment, motor control centers, and general load-switching applications where a 120-volt control coil is specified. It is used by electrical contractors and HVAC service technicians in both new-installation and replacement scenarios. Typical applications include compressor motor switching, fan motor circuits, and other inductive or resistive load control tasks where reliable, repeatable switching performance is required.

Key Features

• 120-volt coil rating matches standard line-voltage control circuits
• Built for switching inductive loads such as compressors and motors
• Designed for use in HVAC, motor control, and commercial electrical panels
• OEM-style replacement form factor for direct service swap-outs

Compatibility

Designed as an OEM-style replacement contactor for 120-volt coil applications in HVAC and motor-control installations. No specific compatible model numbers were provided in the product data.

Installation Notes

Installation should be performed by a licensed electrician or certified HVAC technician in accordance with the NEC and applicable local codes. Disconnect and lock out all power to the panel or equipment before removing the existing contactor or installing a replacement. Verify that the coil voltage, load voltage, and amperage ratings of the replacement contactor match the original equipment specifications before energizing. Do not install with power live or bypass the contactor in a permanent load-carrying configuration.
